Hmmm.. Since one is Lying and the other is telling the truth, you ask the first one 'is 1+1=3'... If he answers 'yes' then u know he is the lying one, hence u ask the other one 'is this the stairway to heaven' and he will tell u the truth..
On the other hand, if the first one answers 'no' means he is the one telling the truth, then the other guard is the liar, hence when u ask the second question, u just follow the opposite answer that he gave..
I think this settles it..
